    {

        Scanner input = new Scanner(System.in);
         int max = 10;
         ClassDataArrayarr,others;             //reference to Array
         others = newClassDataArray(max);

        others.insertOther("Jane", "Wilson", 453.4);
        others.insertOther("Google", "Walmart", 2343.5);
        others.insertOther("Amazon", "Ebay", 32000.0);

        others.displayOther();

        System.out.println("Enter one of the abovesalary");
         double dou =input.nextDouble();
        boolean trueOrFal = others.deleteOther(dou);
        System.out.println(" Deleting " +dou);

        if(trueOrFal == true)
           others.displayOther();
         else
           System.out.println("No such salary in our database");
    }
}

class Chray
{
       private String stt;
       private String lstt;
       private double dr;
       private static int count =0;
       public Chray()
       {
          count +=1;
       }
       public Chray(String x, Stringz, double y)
       {
           stt = x;
           lstt = z;
           dr = y;
       }
       public void est()
       {
           System.out.println(" The name is " + stt+" " +lstt +", salary is"+dr);
       }
       public double getAmt()
       {
            return(dr);
       }
}
class ClassDataArray
{
     private Chray b[];
     private int nOther;

    public ClassDataArray(int oMax)
     {
         b = newChray[oMax];
         nOther = 0;
     }
     public void insertOther(String last,String first, double sal)    //put person intarray
     {
         b[nOther] = newChray(last, first, sal);
         nOther++;
     }
     public void displayOther()
     {
         for(int i=0;i<nOther;i++)
            b[i].est();
     }
     public boolean deleteOther(doublesearchAmt)
     {
         int j;
         for(j=0;j<nOther; j++)
            if( b[j].getAmt() == (searchAmt))
                break;

         if(j ==nOther)
            return false;
         else
         {
            for(int k=j; k<nOther; k++)
                b[k] = b[k+1];
            nOther--;
            return true;
         }
     }
}

Explanation / Answer

System.out.println("Enter one of the above salary");
         double dou =input.nextDouble();
Replace that with JOptionPane.
String enter = JOptionPane.showInputDialog("Enter one of theabove salary"); double dou =Double.parseDouble(enter);
Don't forget to import the below.
import javax.swing.JOptionPane;
